Title:
POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/082134
Kind Code:
A1
Abstract:
[Problem] If there is poor adhesion between double-sided tape and a protection film in a polarizing plate, then when said plate is subjected to shock when transported, dropped, etc., during a step, forces will concentrate in the protection film, which is the portion where the polarizing plate and a backlight unit are joined, and the polarizing plate will come away from the backlight. Accordingly, there has been a need to provide: a polarizing plate with which it is possible to prevent peeling of the double-sided tape due to the shock resulting from transportation, dropping, etc., during the steps subsequent to the joining of the backlight and the polarizing plate in which the protection film has been integrated; and a liquid-crystal display device in which the polarizing plate is used. [Solution] A polarizing plate that has a polarizer, a protection film (A) and a coating layer, in the stated order, wherein the mean spacing Sm between protrusions and recesses on the surface of the coating layer on the far side from the polarizer is 10 μm or less.
